<p>Well, here's my question I guess: will we not want a separate repo for book/docs/etc. that go beyond stdsimd? Or are those close enough that we're just going "eh why not"?</p>

<p>so as i understand it, a git sub-module just points at a secondary repo and a specific commit in a specific branch, right?</p>

<p>I think if we view stdsimd as a repo eventually for absorption by rust-lang/rust then it's a little dicey to put secondary content in.<br>
Yeah but when you compile rustc by default you will pull those submodules in.</p>

<p>i think that stdsimd will probably eternally live as its own repo and be pulled in periodically. For example, i don't think <code>stdarch</code> would ever get merged into rust-lang/rust itself</p>

<p>the built in targets that rust ships are with sse/sse2, but you could use a custom target to have x86_64 as your arch but not have sse/sse2 enabled for that custom profile</p>

<p>but also i think we have some soundness issues with x86_64 without sse/sse2 enabled because they change the call ABI and the standard library is pre-built with them on and so calling the standard library is UB, which is why you'd have to use a fully custom target profile with a custom build of core/alloc/std</p>
